HRC:58-62 spring steel hardened and shock-resistant small hole slotting tool shanks are tested for hardness, precision, and other tests before leaving the factory to ensure that the products are of high quality and higher precision.

1. Stronger rigidity
The shank is molded in a single pass with carburizing and quenching process to make it more rigid and abrasion resistant.
2.Wider application
Suitable for CNC machining centers, CNC machine tools, milling machines and other equipment.
3.Whole Precision Grinding
The surface of the toolholder has been ground through the whole finishing process, and is highly glossy and bright.
4. Longer life
The toolholder has been tested for tens of thousands of times and has a longer life than ordinary toolholders.
5.Overall chamfering
The corners of the knife shaft have been chamfered by fine grinding and rounded without pulling.
6. Strong anti-vibration
Strong anti-vibration of the toolholder, up to 8 times anti-vibration.
7. Tight seams are not easy to collapse the blade.
The knife shaft is heat-treated, not easy to produce physical deformation, the blade and the knife shaft are tightly closed, the blade does not chipping.
8.Overall fine grinding and chamfering treatment
The surface has been finely ground and plated, and the bottom has been chamfered, so the overall precision is higher.
